Can you provide more details of this - logs etc.? The bug was reported for
CentOS/RPM and was due to regression from https://launchpad.net/bugs/710799. Also, 710799 was not ported to PS 5.6 (but it is in PXC 5.6 though, along with fix of 710799), so this issue is not there for RPM either (for PS5.6).
